A simple way to describe Internet of Things (IoT) is a method of controlling or monitoring a device through the Internet. The device, often embedded with sensors, software, network connectivity and necessary electronics that enables them to collect and exchange data.

IoT is here and becoming an increasing topic of interest among technology giants and business communities. It’s a concept that not only has the potential to impact how we live but also how we work.

Yes, everyone like to take express way. I learned the hard way 🙂 yet still like to take the faster method. I would like to share about using the Jumper Wire for Pin Header. I just kind of fall in love with this jumper wire.

Ever think to create a wireless servo controller to control movement of servo motor at a distance? If yes, this tutorial is totally applicable to you. In this tutorial, a wireless servo controller circuit will be established and a servo motor will be controlled wirelessly from a computer through a Servo Control Panel GUI provided by Cytron Technologies.

Yes, it’s really hard to think of a robot with only 4 RC servos without any other actuator. The most common robot is wheel robot with only 2 360 degree rotate RC servos. But, actually you can notice that there is other examples of robot that build from 4 RC servos. One of them is Biped Walker. Thus, today i try to build this robot to test the performance. Another reason is recently we have come out with new product called IFC-RS08 which stand for RC Servo Card (8 Channel RC Servo Controller) and would like to build a application from this product. The construction are pretty easy if compare with other 6 RC Servo Biped. I use roughly 3-4 hours to successfully build and program this robot.

Bluetooth wireless communication is becoming more and more common recently. In response to this trend, Cytron Technologies has came up with a new Bluetooth module called BlueBee, which provides hobbyists a wireless remote control on their microcontroller circuits thus robots through serial port communication service attached with BlueBee. In the section, a simple project will be constructed to illustrate how to use BlueBee for wireless communication to interface another Cytron product, breadboard friendly Arduino, BBFuino to control LEDs.

Nowadays, most hobbyist like to use RC servo motor to control their robot or others than that which need a precise position while a cheapest price. For this project, we are going to discover how to control 2 RC servo motor together using Arduino Duemilanove with Arduino Input Shield.
